Commit 63ab25ebbc (kgdbts: unify/generalize gdb breakpoint adjustment)
introduced a compile regression on sparc.

kgdbts.c: In function 'check_and_rewind_pc':

Simply add the correct macro definition for instruction pointer on the
Sparc architecture.

ae7bd11b47 clocksource: Change __ARCH_HAS_CLOCKSOURCE_DATA to a CONFIG option
The machinery for __ARCH_HAS_CLOCKSOURCE_DATA assumed a file in
asm-generic would be the default for architectures without their own
file in asm/, but that is not how it works.

Replace it with a Kconfig option instead.

b7798d28ec x86: Make Dell Latitude E5420 use reboot=pci
Rebooting on the Dell E5420 often hangs with the keyboard or ACPI
methods, but is reliable via the PCI method.

[ hpa: this was deferred because we believed for a long time that the
  recent reshuffling of the boot priorities in commit
  660e34cebf fixed this platform.
  Unfortunately that turned out to be incorrect. ]

f299bb9527 arm: davinci: Fix low level gpio irq handlers' argument
Commit 7416401 ("arm: davinci: Fix fallout from generic irq chip
conversion") introduced a bug, causing low level interrupt handlers to
get a bogus irq number as an argument. The gpio irq handler falsely
assumes that the handler data is the irq base number and that is no
longer true.

Set the irq handler data to be a pointer to the corresponding gpio
controller. The chained irq handler can then use it to extract both the
irq base number and the gpio registers structure.

770e1ac5f2 powerpc/mm: Fix memory_block_size_bytes() for non-pseries
Just compiling pseries in the kernel causes it to override
memory_block_size_bytes() regardless of what is the runtime
platform.

This cleans up the implementation of that function, fixing
a bug or two while at it, so that it's harmless (and potentially
useful) for other platforms. Without this, bugs in that code
would trigger a WARN_ON() in drivers/base/memory.c when
booting some different platforms.

If/when we have another platform supporting memory hotplug we
might want to either move that out to a generic place or
make it a ppc_md. callback.

5da0ef9a85 x86: Disable AMD_NUMA for 32bit for now
Commit 2706a0bf7b ("x86, NUMA: Enable CONFIG_AMD_NUMA on 32bit
too") enabled AMD NUMA for 32bit too.  Unfortunately, SPARSEMEM
on 32bit had rather coarse (512MiB) addr->node mapping
granularity due to lack of space in page->flags.  This led to
boot failure on certain AMD NUMA machines which had 128MiB
alignment on nodes.

Patches to properly detect this condition and reject NUMA
configuration are posted[1] but deemed too pervasive for merge
at this point (-rc6).  Disable AMD NUMA for 32bit for now and
re-enable once the detection logic is merged.

d34c1fcddc ARM: S3C2440: fix section mismatch on mini2440
If mini2440_init() is in __init, mini2440_parse_features() should also
be in __init. Fixes:

(.text+0x9adc): Section mismatch in reference from the function mini2440_parse_features.clone.0() to the
(unknown reference) .init.data:(unknown)
The function mini2440_parse_features.clone.0() references the (unknown reference) __initdata (unknown).

cb26a7b1c1 ARM: S3C24XX: drop return codes in void function of dma.c
Commit bb072c3c (ARM / Samsung: Use struct syscore_ops for "core" power
management) turned s3c2410_dma_resume_chan() from int to void. So, drop
the actual return values, too. Fixes:

arch/arm/plat-s3c24xx/dma.c: In function 's3c2410_dma_resume_chan':
arch/arm/plat-s3c24xx/dma.c:1238:3: warning: 'return' with a value, in function returning void

5838e9b8da ARM: S3C24XX: don't use uninitialized variable in dma.c
Commit 8970ef47 (S3C24XX: Remove hardware specific registers from DMA
calls) removed the parameter dcon in s3c2410_dma_config() and calculates
it on its own. So the debug-output for the old parameter can go, too.
Fixes:

arch/arm/plat-s3c24xx/dma.c: In function 's3c2410_dma_config':
arch/arm/plat-s3c24xx/dma.c:1030:2: warning: 'dcon' is used uninitialized in this function

ee339fe63a xen/pci: Move check for acpi_sci_override_gsi to xen_setup_acpi_sci.
Previously we would check for acpi_sci_override_gsi == gsi every time
a PCI device was enabled. That works during early bootup, but later
on it could lead to triggering unnecessarily the acpi_gsi_to_irq(..) lookup.
The reason is that acpi_sci_override_gsi was declared in __initdata and
after early bootup could contain bogus values.

This patch moves the check for acpi_sci_override_gsi to the
site where the ACPI SCI is preset.
